Claims

1. An electric vehicle having an electric motor as its driving source, The system comprises one or more processors configured to generate a simulated engine sound and output the simulated engine sound from a speaker mounted on the electric vehicle. The one or more processors described above are: The load weight of the electric vehicle is obtained, As the load weight increases, the sound pressure of the simulated engine sound is increased. It is configured in such a way Electric vehicle.

2. An electric vehicle according to claim 1, It is configured to be able to tow other vehicles. The one or more processors described above are: The status of the towing by the electric vehicle is determined, When the electric vehicle is performing the towing, the sound pressure of the simulated engine sound is increased. It is configured in such a way Electric vehicle.

3. An electric vehicle according to claim 1 or 2, The accelerator pedal and A simulated shifter that mimics the operating mechanism used for shifting gears in a manual transmission vehicle, A control device that performs torque control to control the motor torque output by the electric motor, Furthermore, The torque control includes a manual mode in which the motor torque is changed in response to the operating state of the accelerator pedal and the simulated shifter. Electric vehicle.

4. An electric vehicle according to claim 3, In the manual mode, the control device The output characteristics of the electric motor are changed such that the motor torque increases in the low-speed range as the load weight increases. It is configured in such a way Electric vehicle.
